Hey - I own a 2002 Chrysler sebring coupe, (built in 2001) and I wanted to install the RB4 navigation unit in it. My car has the two 7 pin connectors for the radios, and I know the RB4 has the 22 pin connector. I got the adapter, but I know I need to make a few modifications to get the button backlights to work properly. If anyone has been able to install the RB4 unit into these older cars (2001 and older) and has been able to get the backlights to work please tell me what modifcations I need to do. Thanks so much
